How China’s record-breaking maglev train silenced ‘tunnel boom’
SMRTR summary
Chinese engineers developed a porous 328-foot buffer that reduces "tunnel boom" by 96% when high-speed maglev trains exit tunnels. This breakthrough allows air to vent gradually like a silencer, solving a critical problem for China's 373 mph maglev trains which could soon offer faster, cheaper alternatives to domestic flights while producing seven times less carbon dioxide emissions than air travel.
